Parental Socialization, School Adjustment and Cyber-Aggression among Adolescents

The objective of the present study is to analyse the relationships between parental socialization styles—indulgent, authoritarian, authoritative and negligent, school adjustment (social integration, academic competence and family involvement) and cyber-aggression (direct and indirect) in adolescents. Participating in this study were 1304 Spanish students of both sexes (53.1% girls), aged between 12 and 18 years (M = 13.87, SD = 1.33). Multivariate analyses of variance were performed. The results showed significant relationships between parental socialization styles, school adjustment and cyber-aggression. It was observed that adolescents from indulgent and authoritative families showed greater academic competence and greater family involvement. Additionally, the children from authoritarian families displayed greater involvement in direct and indirect cyber-aggression behaviours. The results obtained and their implications are discussed in the final section.


Introduction
Socialization is defined as a learning and internalization process through which the values, habits and cultural norms necessary for adaptation to a given society are acquired [1][2][3][4]. One of the most relevant socialization contexts, especially in childhood and adolescence, is family [5][6][7][8].
In the field of family socialization, parental styles are among the constructs to have received most attention among researchers. Since the first studies conducted by Baumrind [9,10], a two-dimensional model has been consolidated, based on two orthogonal axes: responsiveness or involvement/acceptance, and demandingness or severity/imposition [11][12][13]. Based on the combination of both axes, four parental styles have been identified [12][13][14][15][16]: indulgent (high involvement/acceptance and low severity/imposition); authoritative (high degree of involvement/acceptance and high severity/imposition); authoritarian (low involvement/acceptance and high severity/imposition); and negligent (low involvement/acceptance and low severity/imposition). Authoritative and indulgent styles have been found to be associated with better adjustment in children in different spheres, although cultural differences exist regarding the effectiveness of these styles [17]. While in Anglo-Saxon culture the authoritative style has been identified as the most associated with the adjustment of children [10,11,13,16,18,19], in Mediterranean culture the indulgent style is the most adaptive [14,[20][21][22].
In relation to adjustment at school, it has been observed that parents have a significant influence on the academic and social success of students [23,24]. School adjustment is defined as the ability of students to adapt to the educational context and includes aspects such as academic performance, adaptation to school standards, respect for teachers as figures of authority, student attitude towards school and participation in school activities [25][26][27]. According to Cava, Povedano, Buelga, and Musitu [28], school adjustment in adolescence is associated with collaboration and involvement on the part of families in the educational processes and experiences of their children [29,30].

Participants and Procedure
The sample consisted of 1304 adolescents of both sexes (53.1% girls) aged between 12 and 18 (M = 13.87, SD = 1.33), enrolled at four Compulsory Secondary Education (ESO) centres in the autonomous communities of Andalusia, Aragon and Valencia (Spain). For the selection of the sample, random group sampling was used in the geographical area of Andalusia, Aragon and the Autonomous Community of Valencia. The primary units of the sample were the urban and rural areas in the three autonomous communities. The secondary units were public and private secondary schools in each area. Classes were not treated as tertiary units, as all classes from the first to the fourth year at the selected centres were included in the study. A series of prior analyses of differences in means yielded the variables the object of the study, as a function of the location of the centres and their public or private status. No statistically significant differences were observed.
Data for this research were compiled as part of a broader study on violent behaviour in adolescents in Spain (Reference: PSI2015-65683-P). The study was approved by the ethical committee of each participating university (DPS.EEL.01.15). Additionally, the study complies with the ethical values required in research with human beings and respects the fundamental principles included in the Helsinki Declaration. Once permission had been obtained from the educational centres to carry out the research and active informed consent from the families had been granted, the battery of instruments was administered in two different sessions of approximately 45 minutes at the educational centres.

Instruments
Parenting Styles. The Parental Socialization Scale (ESPA29, [14]) was used based on the two-dimensional theoretical model of parental socialization [12,15]. This scale consists of 232 items that measure, on a response scale ranging from 1 (never) to 4 (always), parents' performance in 29 situations that are representative of everyday family life in Western culture: 13 that represent situations of obedience with family norms (e.g., "If I take care of my things and am clean and properly dressed") in which adolescents value the frequency with which parents show affection (e.g., "He/she shows warmth"), α = 0.96; indifference (e.g., "He/she seems indifferent"), α = 0.95; and 16 that refer to situations of disobedience with these norms (e.g., "If I leave home to go somewhere without asking anyone for permission") in which adolescents rated the frequency with which parents respond through dialogue (e.g., "He/she talks to me"), α = 0.95; indifference (e.g., "It's the same to him/her"), α = 0.90; verbal scolding (e.g., "He/she scolds me"), α = 0.94; physical punishment (e.g., "He/she hits me"), α = 0.94; and revoking privileges (e.g., "He/she takes something away from me"), α = 0.95. The family score in acceptance/involvement was obtained by averaging the responses for affection, dialogue, indifference and dissatisfaction (in the last two sub-scales the responses were inverted by being negatively related with the dimension). The family severity/imposition score was obtained by averaging responses in verbal scolding, physical punishment and revoking privileges [13,15]. Both family indices ranged between 1 and 4 points, high levels of acceptance/involvement and severity/imposition corresponding to high scores. Based on these scores, the family socialization style was defined as authoritative, indulgent, authoritarian or negligent. Cronbach's alpha in acceptance/involvement was α = 0.90, and the values obtained in severity/imposition were α = 0.96.
School Adjustment. The Scale of Teacher's Perception of School Adjustment (PROF-A, [28]) was used. This scale consists of 13 items that measure teachers' perception of student adjustment based on a response scale ranging from 0 (very low/very bad) to 9 (very high/very good). The scale consists of three dimensions: social integration (e.g., "The student's relationship with his/her classmates"), α = 0.92; academic competition (e.g., "The student's interest in and attention to what is done in class"), α = 0.95; and family involvement (e.g., "The degree of the family's involvement in the school monitoring of the child"), α = 0.93. Cronbach's alpha for the scale was α = 0.93.
Cyber-aggression. The Cyber-Aggression Scale (CybAG_R, [58]) was used. This scale consists of 24 items that measure involvement in violent behaviours through the use of digital media during the last 12 months, based on a response scale ranging from 1 (never) to 5 (many times/more than 10 times). The scale consists of two dimensions: direct cyber-aggression (e.g., "I have taken a person's mobile phone and used it to send embarrassing photos, videos or messages to get them into trouble"), α = 0.94; and indirect cyber-aggression (e.g., "I have passed myself off as someone else to do bad things on the Internet or using a mobile phone"), α = 0.86. Cronbach's alpha for the scale was α = 0.94.

Data Analysis
Firstly, the distribution of the families was calculated according to the educational style, as well as the means and standard deviations obtained in each of the dimensions of the model (see Table 1). Subsequently, a multivariate factorial design (MANOVA, 4 × 2) was carried out, with the SPSS statistical program (version 20, Pablo de Olavide University, Seville, Andalusia, Spain) considering parental socialization styles (indulgent, authoritative, authoritarian and negligent) and gender (boys and girls) as fixed factors to analyse the possible effects of interaction. The three dimensions of teachers' perception of students (social integration, academic competence and family involvement) and the two dimensions of the cyber-aggression scale (direct and indirect) were considered as dependent variables. Finally, univariate tests (ANOVAS) were calculated to study the statistically significant differences in the variables and the Bonferroni post-hoc test (α = 0.05) was performed.

Discussion
The objective of the present study was to analyse the relationships between parental socialization styles (indulgent, authoritarian, authoritative and negligent), school adjustment (social integration, academic competence and family involvement) and cyber-aggression (direct and indirect) in adolescents. The results obtained indicated that adolescents from families using indulgent or authoritative styles displayed greater academic proficiency and family involvement. However, no significant differences in social integration were observed according to the style of socialization, thus partially confirming the first hypothesis. Previous studies have highlighted that indulgent and authoritative styles enhance teenagers' academic proficiency [89][90][91], probably due to greater parental involvement in school [92]. In this sense, the participation of families in the educational context of their children promotes the latter's success at school, more positive self-esteem and greater self-confidence, aspects that, in turn, promote school adjustment [31,[93][94][95][96]. However, social integration has proven to be equivalent in all four styles, probably because parents are more involved in academic and performance-related issues and focus more on this social dimension when problems of school integration emerge. These results underscore the importance of analysing school adjustment from a multi-dimensional perspective taking into account aspects that transcend academic performance. More research is needed to analyse the role of family variables on social integration.
With respect to cyber-aggression, as hypothesized, adolescents from authoritarian families showed greater involvement in direct and indirect cyber-aggressive behaviours, while involvement in such behaviours was similar in adolescents brought up by parents employing an indulgent, authoritative and negligent style. These results are in line with the conclusions reported in previous research that the authoritarian style is the most associated with involvement in violent behaviour in adolescence [55,57,81].
The parental practices of authoritarian families are characterized as being coercive and imposed, and based on submission, obedience and control, with a low level of affection and involvement, expressed through cold and empathic communication. These findings suggest that adolescents from authoritarian families transfer this type of practice to their relationships with peers in the virtual environment [97] and consider direct and indirect forms of cyber-aggression to be acceptable [61,62,98,99].
In this sense, the results infer that the adolescents most involved in cyber-aggression behaviours often come from families in which low levels of affection and coercion prevail, probably because the virtual space constitutes an environment beyond the eyes of adults.
The results for the third hypothesis indicated that girls from indulgent families showed greater social integration than boys from indulgent and negligent families, while boys from authoritarian families obtained the highest scores in both direct and indirect cyber-aggression; hence, the hypothesis was partially confirmed. Although girls displayed greater school adjustment in terms of social integration and academic proficiency, the interaction effect revealed that girls from indulgent families (with high levels of affection and discipline based on communication and self-revelation) were the most socially integrated at school. These results infer that both the school environment and family relationships constitute socialization scenarios in which gender has a transversal effect. Thus, for adolescent girls, social relationships, both with peers and with teachers, as well as emotional involvement in family and at school, acquire greater importance than for boys [100].
Therefore, the confluence of parental practices with formal school socialization processes seems to enhance social integration in girls, who also usually present adequate academic proficiency. Thus, positive attitudes towards school imply more positive social relationships [101][102][103], greater academic effort and greater participation in school tasks [40,73,74,94,104,105], aspects which are socially reinforced in girls. Furthermore, previous studies have shown that girls display greater empathy and pro-sociability in the educational context [106,107], aspects that seem to facilitate their social integration in the classroom.
In contrast, boys from authoritarian families showed the highest levels of involvement in cyber-aggression (direct and indirect) compared to the other groups studied. These results are in line with those reported in previous studies [80][81][82][83][84][85][86]. In this sense, the results obtained here suggest that in the authoritarian style, based on coercion coupled with poor communication, the socialization of gender roles fosters greater assimilation of traditional patterns in which coercion and imposition are less censored traits in boys [98][99][100], resulting in aggression and hostile behaviours being perceived as legitimate or justifiable behaviours of "masculinity" [108,109]. Cyberaggression could partly explain why adolescent males tended to report that frequent Internet use affected their health [110]. The authors of this study believe that future research should incorporate gender socialization measures linked to socialization styles for a more in-depth analysis of socialization styles and their implications.

Limitations
Finally, the results of the present study have certain limitations. The cross-sectional nature of the study design did not allow casual relationships to be established. Therefore, future research incorporating different time panels would allow us to explore the differences identified in the study. In view of the cultural differences observed with respect to socialization styles and their relationship with the adjustment of children, it would be worthwhile carrying out further research in other countries in southern Europe, in order to compare the results obtained and thus draw conclusions regarding the influence of parental socialization on school adjustment and children's involvement in cyber-aggression in the Mediterranean context. Future studies should use other statistical techniques that make it possible to control variables such as the socio-educational level and occupation of the parents. Additionally, in the present study, the importance of the gender of the teachers in the perception of the school adjustment of the children-as well as the time of Internet use, was not analysed and could be addressed in future research.

Conclusions
The results of this research show that parental socialization styles play a key role in the school and behavioural adjustment of adolescents. The findings show that parenting styles defined as high acceptation/involvement, such as the indulgent and authoritative styles, are related to better school adjustment and low involvement in both direct and indirect cyberaggression. Thus, affection, parental involvement, empathic communication and dialogue enhance the school adjustment of children, probably because parents who embrace such socialization styles are also involved in the schoolwork and social relations of their children, thus promoting the development of academic, social and behavioural skills that are valued positively at school. Therefore, results of the present study have important implications for practice. Evidence from this study highlights that family-school interactions in the individual, group and institutional spheres should be promoted. Positive and fluid communication between parents and teachers could contribute positively to students, not only at academic level but also in relation to such relevant issues as behavioural problems in the classroom and on the Internet. Finally, the findings of this study confirm the importance of considering the influence of gender socialization processes, which are transmitted to boys and girls, in the design of educational programs and strategies to prevent cyber-aggression.
